1. The Federal Court System

2. Equal Justice for All
Courts settle civil disputes between private parties, a private party and the government, or the United States and a state or local government.
Each side presents its position.
The court applies the law and decides in favor of one or the other.
Courts also hold criminal trials for people accused of crimes.

3. Equal Justice for All
Witnesses present evidence and a jury or a judge delivers a verdict of guilt or innocence.
All accused people have the right to a public trial and a lawyer.
If they cannot afford a lawyer, the court will appoint and pay for one.

4. Equal Justice for All
Accused people are considered innocent until proven guilty. They may ask for a review of their case if they think the court has made a mistake.
The goal of the legal system is equal justice under the law.
This goal is difficult to achieve.

5. The Federal Court System
Article III established a national Supreme Court and gave Congress the power to establish lower federal courts.
Over the years, Congress set up three levels in the federal court system
district courts at the bottom
appeals courts in the middle
the Supreme Court at the top.
Each state also has its own laws and court system.

Federal courts hear disputes between a foreign government and either the U.S. government or an American private party.

8. The Federal Court System
Admiralty and maritime laws concern accidents or crimes on the high seas. Federal courts hear cases involving these laws.
Federal courts hear cases involving U.S. diplomats.
For most of these eight areas, federal courts have exclusive jurisdiction-only they may hear and decide such cases.

9. The Federal Court System
Most U.S. court cases involve state law and are tried in state courts.
In a few circumstances, the state and federal courts have concurrent jurisdiction-they only share jurisdiction and either may hear the case.
